Had this moped for almost 6 years and it hasn't failed me once through almost 8k miles. Many small modifications that I've done all myself. Recently decided to bite the bullet and add the jammer clutch to the mods. Took that transmission apart 5 times to try to make it work. Had to replace and shorten the inner allen bolts, grind open the splines, and source a washer for it since it was catching the bell. (Although treatland says the washer is no longer needed per email with dana). Did all that and it still made the pedals spin backwards insanely fast and would turn off as soon as the back wheel hit the ground. So after all those mods to the jammer I said screw it im putting my stock 1st gear clutch back on which has fairly new pads and a 20lb spring that I've ran for over 1000miles with no issue.
YES the sprag is installed right and didnt slip.
YES all the shims are there and properly installed.
Pedals forward fine, kicking it to start is no issue, drives completely fine around the block.
But as soon as i put it on the stand and rev, the pedals rolls backwards as I rev.
Wtf is wrong?!
